      Release Notes: There have been no new features since 10/31, this release is just recompiled to support "older" 1.6 JRE users, as the author had accidentally set the IDE to 1.7.

            Release Notes: This release re-architects the underlying memory event handler model to include CPU opcode/operand memory accesses. A new memory heatmap view has been added to metacheat (press END to activate); this lets you see active reads/writes/executes in memory as they happen. It fixes graphics glitches in hi-res mode. It improves RGB Mode 7 support to auto-detect RGB mode. It fixes a Disk ][ bug that caused hangups in programs like Apple Desktop ][. This is a very stable release.
